The live sound & landscape of the Bitcoin network.
A playful experiment by Spotkolours — turning the live Bitcoin network into sound and scenery. Reads public chain data only (mempool.space): no wallet, no funds, no custody, nothing to buy or sell. Made for curiosity, not profit. Got an idea? I'd love to hear it — gareth@spotkolours.com.
A calm, living portrait of the Bitcoin network — a way to hear it breathe instead of watching numbers tick. Everything you see and hear is generated live from real Bitcoin activity. It reads public data only: no wallet, no funds, nothing to buy or sell.
Turn your sound on and press Play. Give it a few seconds to connect, then sit back — the music and landscape keep evolving on their own as the network changes.
Bitcoin confirms a new "block" of transactions roughly every ten minutes; in between, transactions wait in a queue called the mempool. When the network is quiet the music stays soft and mellow; when it gets busy the beat tightens, the bass deepens, and the scenery speeds up — so you can feel whether it's a calm afternoon or a rush hour.
The glowing terrain is the network too. Fresh ground is constantly generated and flies toward a bright "sun" on the horizon — that sun is the next block forming, and it flashes gold the moment a block is confirmed. Small coloured cubes mark real events that just changed the music: gold = a new block, orange = fees, green = mempool, blue = activity.
Every ten minutes or so a block arrives — the highlight. The music takes a brief breath, plays a little flourish, and resets into a fresh melody and key based on that exact block, while the horizon flashes and a shooting star crosses the sky.
Caught a block you liked? Tap Share at the top. It makes a cover image for that exact block — its number, tempo and fee — and lets you post it to your phone's share sheet, X, WhatsApp or Telegram, or just download the image and copy the caption.
Keep the sound on. It runs best on a computer — the moving landscape is graphics-heavy on older phones. If your connection drops, it quietly switches to a simulated feed so the music keeps playing. It's completely safe to explore: it only reads public Bitcoin data and can't move or spend anything.
